REMOVAL & INSTALLATION
See Figures 1 through 9
The hydraulic concentric bearing incorporates the release bearing and the slave cylinder in a single assembly.
The hydraulic concentric bearing completely encircles the transmission input shaft. In operation, the piston movement causes the bearing to move in a straight line direction.
The hydraulic concentric bearing is serviced as an assembly only. The release bearing portion of the assembly is permanently attached to the piston. The hydraulic lines are also permanently attached.
- Disconnect the negative battery cable.
- Raise and support the vehicle safely.
- Remove the transmission.
- Disconnect the clutch master cylinder fluid line.
- Remove the insulator plate bolts and slide the plate off the bleed line.
- Remove the concentric bearing retaining nut.
- Remove the concentric bearing from the transmission input shaft. If the bearing will be reused, secure the bearing and piston with rubber bands.
- Inspect the bearing mounting pin and replace the front cover if the pin is damaged. Install the concentric bearing on the transmission input shaft.
- Guide the bearing fluid and bleed lines through the openings in the clutch housing.
- Position the bearing boss on the mounting pin and seat the bearing against the transmission. Install a new retaining nut and unhook the T-handle straps retaining the bearing.
- Install the insulator and plate.
- Install the transmission and transfer case and connect the clutch master cylinder fluid line.
- Fill and bleed the clutch hydraulic system.
The clutch master cylinder, slave cylinder and connecting line are sealed units which must be replaced as an assembly; it is not rebuildable. Refer to the Master Cylinder removal and installation procedure, outlined earlier in this section.
The hydraulic concentric bearing (slave cylinder) is not rebuildable and must be replaced as an assembly if defective.
